Japanese Patent JP2018028250

A

PROBLEM TO BE SOLVED: To provide a pipe member connection device using a wedge member which is smoothly guided in a vertical direction by firmly fixing a horizontal steel pipe of a vertical support post having no part where the outer periphery of a mounting device protrudes from the outer periphery of the horizontal steel pipe and a wedge member does not enter into the horizontal steel pipe.SOLUTION: Provided is a connection device for connecting a horizontal steel pipe 2 to a vertical support post 1 for temporary scaffolding. The vertical support post 1 has a flange 11 having a rectangular fitting hole 111. An attachment member 4 is fixed to the end part of the horizontal steel pipe 2. The attachment member 4 has a notch into which the flange 11 can be inserted. A biforked wedge member 5 is inserted into a through hole in a vertical direction. The attachment member 4 has a support post fixing part which comes into close contact with the outer periphery of the vertical support post 1 in a predetermined wide range. The lower part of the attachment member 4 has a shape not protruding from the horizontal steel pipe 2 toward the vertical support post 1 except a part along the vertical support post 1. When connecting the horizontal steel pipe 2 into the vertical support post 1, the flange 11 is inserted into the notches of the horizontal steel pipe 2 and the attachment member 4. The wedge member 5 is inserted while bridging front edge part of the flange 11 by the biforked part to connect to the flange 11.SELECTED DRAWING: Figure 1
